Playwright Ben Eisenberg sits in a Starbucks on the eve of the first rehearsal of his stage adaptation of Don Quixote. There’s just one problem—he hasn’t written it. He hasn’t written anything in years, and his status as wunderkind playwright is quickly fading to has-been hack. His agent is apoplectic, the producer’s advance is long since spent and adapting a 1,000-page Renaissance adventure is beginning to feel a bit like tilting at windmills. But then—whether from a stroke of genius or a near-lethal dose of caffeine and sleep deprivation—Starbucks itself begins to transform, and the errant knight arises in this delightfully theatrical and hilarious retelling of Cervantes’ classic tale.
